I am getting some new fire doors and linings. My old ones have stop of 25mmx50mm which I thought was usual for fire doors. I see the new linings come with 14.5 x 32mm door stops
Do you mean what if intumescent strips are not installed?
In that case, the doorset is not considered fire resisting
If you don't fit any strips, then the stops should really be increased as per "the oldern days", but then the door set might fail any check regarding compliance to current standards
